A novel glial fibrillary acidic protein (GFAP) mutation, Y257C, is reported in a patient with adult-onset Alexander disease. This is the oldest reported case with confirmation of a GFAP mutation. Onset was late in the sixth decade. Genetic analysis of the GFAP gene is recommended in cases of
Pathogenic, dominant, de novo missense mutations in the glial fibrillary acidic protein (GFAP) have been found in the three subtypes of infantile, juvenile and adult Alexander disease. Here we describe four members of an Italian family (32 to 66-yearsold, 2 women and 2 men) affected by adult
The recent discovery of heterozygous de novo mutations in the glial fibrillary acidic protein (GFAP) gene as the cause of infantile and juvenile Alexander disease has shed new light on the long-standing debate whether the adult subtype has the same etiology as infantile and juvenile Alexander
In this report, we describe the case of a new Japanese family (32 to 64 years old; 2 females and 1 male) affected by adult-onset Alexander disease. Clinically, one member (age at onset, 56 years old) developed cerebellar ataxia, another (age at onset, 55 years old) showed cerebellar ataxia and
BACKGROUND
Alexander disease (AxD) is a rare neurological disease, especially in adults. It shows variable clinical and radiological features.
METHODS
We diagnosed a female with AxD presenting with paroxysmal numbness of the limbs at the onset age of 28-year-old, progressing gradually to spastic
Alexander disease (AxD) is a rare, autosomal dominant neurological disorder. Three clinical subtypes are distinguished based on age at onset: infantile (0-2 years), juvenile (2-13 years), and adult (>13 years). The three forms differ in symptoms and prognosis. Rapid neurological decline with a
Alexander disease is a rare disorder of the central nervous system caused by a de novo mutation in the glial fibrillary acidic protein (GFAP) gene. Unlike the much more common infantile form, the juvenile form is slowly progressive with bulbar, pyramidal and cerebellar signs. Herein, we report a
Following the discovery of glial fibrillary acidic protein (GFAP) mutations as the causative factor of Alexander disease (AxD), new case reports have recently increased, prompting a more detailed comprehension of the clinical features of the three disease subtypes (infantile, juvenile and adult).
BACKGROUND
Alexander disease is a rare form of leukodystrophy that involves mainly astrocytes; it is inherited in an autosomal recessive manner and occurs by mutations in the GFAP gene, located on chromosome 17q21. It can occur at any age and its infantile form is characterized by macrocephaly,
Alexander disease (ALXDRD) is a rare astrocytic leukodystrophy caused by GFAP mutations. The adult-onset (AO) variant is usually characterized by gradual onset of spastic ataxia and bulbar symptoms with slowly progressive course. We report two AO-ALXDRD cases with rapid worsening after minor head
Alexander disease is usually classified according to the age of onset, e.g. an infantile form with onset during the first two years of life, a juvenile form with onset in childhood, mainly school age. It has been recognized, however, that the clinical course can be very variable within these groups.
BACKGROUND
Alexander disease (AxD) is an astrogliopathy, resulting from a mutation in the glial fibrillary astrocytic protein gene. Different clinical subtypes have been described, including infantile, juvenile, and adult onset, based upon the age at which symptoms begin. Patients with the
